River Description

This is the best section of the Grass! The character of the run is classic Adirondack "Pool-Big Drop" with sticky holes at high flows. Rainbow Falls, a.k.a. "Large Marge"5.1+ (Bigger than Magilla) and "Twin Falls" IV+ (Beefed up Fowlersville Falls w/o the hole) are the "Big Drops" of note. They are spectacular! There are six other distinctive CL IV-IV+ rapids that are separated by some CL III+ rapids and a few stretches of flatwater. The area is very scenic so relax and enjoy until you approach the next horizon line. The run is essentially roadside, but the road is seldom visible. The road is always river right.

Gauge Information

Gauge Description:



Season: April and May are generally the best months for the Grass, but Oct and Nov also offer windows of boatable flows following three or four days of good rain.

Flows: The USGS gauge on the Oswegatchie in Harrisville provides an "approximation". The benchmarks below have many variables, so make sure you assess each drop yourself, especially at MED and HIGH flows. If Harrisville gauge is rising:

MIN:750-800cfs (3.5') - You will scrape in numerous areas, but have enough for the main drops.
MED: 1100cfs (4.0') - Only slight scraping, but holes are tame.
HIGH: 1700 (4.75') - Ratchet up the difficulty of all rapids at least half a level. Holes are bad!

If Harrisville guage is dropping add 150 cfs to the flows above.

Visual "Gauge": Check the Graffiti on the river right rock just below the bridge in Degrasse. If water is rising and touching the bottom of the "heart", then you can scrape down the wide places and have good water for the drops. If water is dropping then middle of "heart" is the MIN mark.

We took a low water run on this section on 10/21/2007. The log is no longer blocking the left
channel.

There is a river wide log between Large Marge (Rainbow Falls) and "Whip it". It was in the left
channel about 100 yds above whip it. You have to portage it when Harrisville gage is below 900. The
water is at the bottom of the heart on the Degrasse Graffiti

Rapid Descriptions

Large Marge (Rainbow Falls) (Class 5.1, Mile 0.2)

This is the first tree top horizon line you come to. Scout right side then left if you consider running this. It is normally portaged left. Safety is difficult. The hole at the bottom of the falls can be bad at high flows and the wall on the right below the drop is a magnet for flipped paddlers and makes rolling tough.

Whip-it Good (Class IV, Mile 0.6)
The river narrows down and makes a nice continuous set of rapids for about 0.3mi that is punctuated with a river wide hole "Whip-it Good" near the end. At higher flows this hole can be real sticky. Stay left.

Flat Rock Falls (Class IV, Mile 1.3)
Ledge slide drop with multiple lines and a sticky hole at the bottom.

Adrenalin Falls (Stewart Rapid) (Class IV, Mile 3.0)

This 30'(+)ledge slide is a rocket launching pad! Scout right. If you don't see the line think about walking. Hint try and finish between the two Rooster Tails at the bottom right. Getting off-line or flipping can be ugly.

Iron Bridge (Sinclair Falls) (Class IV+, Mile 4.3)
The Iron Bridge crossing the river marks this drop (bridge connects Lake George Rd to Tooley Pd Rd). Watch the hole at the bottom, it can/will eat your lunch, especially at high water. Scout right at Med and low flows, high flows scout left. Portage is easiest left I'm told.

Basford Falls (Class IV, Mile 5.1)
Multiple lines. Left side slide is easier. The center ledges and holes offer a tricky CL V option. Scout the center and right lines from the right. Scout Left line from the left. -

Degrasse Graffiti (Class IV, Mile 6.5)
This rapid looks intimidating, but a great finish to great run. The hole can be sticky at high water.
